CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 400,068, dated March 26, 1889.

Application filed August 7, 1888. Serial No. 282,187. (No model).

To @ZZ whom, it may concern.-

Be 1t known that I, ROBERT LEE EVANS, of

Scottsborough, in the county of Jackson and State of Alabama, have invented a new and useful Improvement in Car- Couplings, of which the following is a specification.

My invention relates to car-couplings, and has for its object to provide a simple and et cient means for the coupling of cars; and it consists in the peculiar construction and combination of parts, as will be hereinafter fully described, and pointed out in the claims.4

In the drawings, Figure l is a perspective view of my improvementas applied to a ear. Fig. 2 is a side elevation, partly in section, of the same as applied to two adjoining cars. Fig. 3 is a detail view ot the pin-holder, and Fig. i is a view of one of the links.

To the end A of the car-body is applied the draw-head B, et' usual construction, which is provided with the pin-openings h h', through which operates the pin C. The pin C is formed ot the lower portion, c, which operates in the draw-head, and with the upper extended portion, c. The upper end of the pin C extends through and is guided in a slot, d, of a bracket, D, extended from the car-body, and about midway its length it is provided with a fixed collar, c2.

Mounted upon the extension c of the link, and resting at its lower end upon the collar c2, is a coiled spring, E, the upper portion, e, of which extends up to and is held in place by the bracket D, as shown. In practical use it is preferred to place aloose collar7 F, upon the pin C, which rests against the lower edge of the bracket D, and thereby serves to assist in steadying the spring and pin when the pin is moved upwardly.

In brackets G G on the ends of the car is journaled a transverse shaft, H, provided at each end with hand-wheels I 'for turning it. Attached centrally to said shaft is one end of a chain, J, the other end of which is secured to the upper end of the pin C, as atj. v

In the lront tace of the draw-head, and to each side of the mouth a, are fromed grooves L L, in which is pivoted the pin-holder M. The pin-holder M consists of a n-shaped bar pivoted at m fm in the grooves L L, as stated, and hasits lower extensions or arms, m m',

arranged to iit in the extensions ZZ of the grooves L. The upper portion, nl?, is extended upwardly and inwardly over the draw-head and extends approximately in the path of the movement of the pin, as shown. The upper end, m2, ot the holder is arranged to drop under the collar c2 of the pin when the same is raised, and to effectively cause the said upper end ot' the holder to automatically drop under said collar. Springs N N are seated in recesses n n in the grooves L L in the draw-heads, which springs normally press the arms m m of the holder outwardly, and thereby force the upper yoke portion, mi, inwardly. By this construction it will be seen that when it is desired to couple the car to another the shaft G is turned and the chain .I is wound thereon, which will pull the pin C up and contract the spring. When the pin. has been raised to a height sutlicient for the lower end of the pin to rise out oli' the recess B of the drawm2 oi' the holder M, which will drop under said catch, and thereby hold the pin in its raised position. Now, as the draw-head of the adjacent car approaches, its link will enter the recess B,'and when the draw-heads close up the projecting arms my m of the support will be struck, the upper edge, m2, will be released from the collar c', the tension of the spring thereby released, the pin C forced down through the link, and thereby coupling the car. The link is formed of a bar, O, having beveled upturned ends o, and provided with elongated slots 0 at cach end. VWhen it is desired to couple cars of different heights, links of the form shown in FigAE are used, which consist of forming the link above described with t-he central portion, o2, bent npwardly, as shown.

From the foregoing description, taken in connection with the drawings, the operation of my invention will be readily understood.

llaving thus described my invention, what I claim as new is-` ,k

l. In a car-coupler; the combination, with the draw-head B, the pin C, having a fixed collar, c2, and means, substantially as described, for raising the pin, of a n-shaped pin-holder adapted to engage the collar c'l of the pin C, said holder pivoted to the draw-head and prohead, the collar c will have passed the edge.
